Evaluation of Eustachian Tube Function With 226 and 1000 Hz Probes in Children Undergoing Tonsillectomy ± Adenoidectomy

Sumeyra DOLUOGLU128 enrolled

Overview

In children undergoing tonsillectomy ± adenoidectomy without eustachian dysfunction, the objective is to control tubal functions with tympanometry utilising probes at 226 Hz and 1000 Hz, as well as measuring the ipsilateral and contralateral acoustic reflexes with a 226 Hz probe. An eustachian function test with a 226 Hz probe (automatic Williams test) and play audiometry are to be conducted on young children, while pure tone audiometry is to be conducted on older children, in the preoperative period, on the first day after surgery and in the second week after surgery. The primary objective is to ascertain whether the tubal functions, which are hypothesised to be impaired on the first day, return at the latest in the second week, with all tests evaluating the eustachian tube both directly and indirectly. The secondary objective is to determine whether this recovery occurs earlier with the 226 Hz probe or the 1000 Hz probe.

In children undergoing tonsillectomy ± adenoidectomy without eustachian dysfunction, tympanometry with 226 Hz and 1000 Hz probes, ipsi and contralateral acoustic reflexes with 226 Hz probe, eustachian function test with 226 Hz probe (automatic Williams test) and play audiometry in young children and pure tone audiometry in older children are aimed to control tubal functions in preoperative period, postoperative day 1 and week 2.

Outcomes

Primary Outcomes

Evaluation the functionality of the eustachian tube with odiometric tests

Evaluation the functionality of the eustachian tube, which was presumed to be compromised on the initial post-adenotonsillectomy day, and ascertainment whether it had recuperated by the second week. Tympanometry with 226 and 1000 Hz probes, eustachian function test with 226 Hz probe, ipsi and contralateral acoustic reflexes with 226 Hz probe and pure tone-play audiometry were performed in all patients one day before the operation. All tests were repeated on postoperative day 1 before the patient was discharged. All tests were repeated at the 2nd postoperative week.

Time frame: 14 days

Secondary Outcomes

Evaluation the functionality of the eustachian tube with tympanometry the 226 Hz and 1000 Hz probes

It was investigated which of the 226 Hz and 1000 Hz probes used in these tests detected earlier recovery findings.

Time frame: 21 days
